TuneLab Piano Tuner - for iPhone, iPad, iPod Touch

TuneLab, the popular piano tuning software that has been used for over 15 years by professional piano technicians around the world, is available for iPhone, iPad, and iPod Touch. You can find the app in the App Store by clicking here:
Here is what the main tuning page looks like:
The bar with the two black squares is called the phase display.  The squares move left for flat and right for sharp.  You tune the piano so that the pattern comes to a stop.  This display is for fine-tuning.

Near the bottom is a graph called the spectrum display.  This display gives additional information about the distribution of sound energy across the frequency spectrum.  If there are several pitches sounding at once, this graph will show a peak for each pitch.  Using this you can do a rough pitch-raise tuning without spending time moving mutes.

The best way to learn all about TuneLab for iPhone is to download the manual right here:
